“ Computer programs emerge as the outcome of complex human processes of cognition, communication and negotiation, which serve to establish the meaningful embedding of the computer system in its intended use context. ”

Hallbeck, M. Susan, Kamal, Abe H. and Harmon, Paul E. (1992): The Effects of Forearm Posture, Wrist Posture, Gender, and Hand on Three Peak Pinch Force Types. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 801-805.

“In many industries the hand is utilized as a fixture, pinching in various wrist postures and forearm postures. In an effort to quantify the effects of wrist posture, forearm posture, gender, and dominant/non-dominant hand upon three peak pinch forces, a study was performed. Three pinch types were tested in this study: index pad pinch, middle pad pinch, and three-jaw chuck pinch force. For each pinch exertion condition, one of five wrist postures were employed: neutral, 45{deg} extension, 65{deg} extension, 45{deg} flexion, and 65{deg} flexion. Each pinch was also performed in one of three forearm postures: neutral, full pronation, and full supination. Ten subjects between 20-25 years of age within each gender category were tested giving a total of 20 subjects. Each subject was asked to build up to his or her maximal voluntary contraction using a modified Caldwell regimen, and hold that pinch level for three seconds. Results were analyzed using analysis of variance (ANOVA) with significant effects (gender, hand, pinch type, wrist posture, and forearm posture) tested using post hoc analysis. The results and their implications are discussed.”
